Title:
CLOCK REPLAY CIRCUIT AND CLOCK REPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2012/029597
Kind Code:
A1
Abstract:
The present invention can be applied to high-speed communication of an equalization technique to a duobinary signal, that proactively uses inter-code interference. In such applications, a clock replay circuit that accurately detects clock timing is required due to the limited margin available for clock timing. Provided is a duobinary clock replay circuit provided with a phase detection circuit that detects phase displacement between an input signal and a clock signal and can output binary values in the current timing by using decision results and previously-assessed binary values, by comparing input signals that have been equalized to duobinary waveforms with a plurality of threshold values.
